When confronted with a small Port Jackson shark, instead of fleeing the scene, Hatheier simply picked it up and plopped it back into the ocean, where it belonged.

"He was pretty distressed and bumping into things, so I just followed him around for a bit ... I just thought I would try and catch him. I just dived on him," Hatheier told Australia's ABC News. "I thought, as long as I keep my hand near its fins it couldn't bite me; I wouldn't have grabbed it by the tail though. I wasn't really scared but I wouldn't have done it with a great white [shark]."

So the next time you run into a problem, assess what's required, steel yourself and coolly, calmly get on with it, one step at a time.
